security
HI
I'm new to knoppix/linux. Using Windows, I always ran Zonealarm firewall. With Knoppix, I feel "exposed" because there is no firewall. On the GRC Shields Up page It says I fail the Stealth test, but all ports show up as closed. Zone Alarm with Windows shows totally stealth.
I have 3 questions-
1-Is linux secure enough to use without a firewall?
2-Can I install a firewall (or other software) when running knoppix live from cd?
3-I understand the obvious security of not writing to the hard drive-only to the ramdisk, which disappears after rebooting. I've even run knoppix successfully with hard drive physically disconnected-so no chance of reading from it either. But does anyone know what kind of things hackers could do through your computer during a session-or is knoppix/linux not vulnerable like windows?

Re: security
--If running from the CD, you should have few worries but you can always run iptables:
http://www.knoppix.net/forum/viewtop...ight=basicprot
(Go with the second post, the 1st one is outdated.) Check out the reference links at the bottom; you should have a basic understanding of iptables before implementing.
--Don't forget to chmod +x the script, and (obviously) run it as root.
--To see what ports are open on your system, ' nmap localhost '.
